'SAWING- IVIACHINE SPECIFICATION forming part of Letters Patent` No.y 290,051, dated December 11, 1883. Application filed July 19, 188.3; (No model.)

To aZZ whom it may concern:

Be it known that I, SOLOMON HIRscnY, va citizen of the United States, residing at Berne, in the county of Adams, State of Indiana, have invented certain new and useful Improvements in Sawing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improved machine for sawing wood, and will rst be described, and then designated in the claims.

In the drawings hereto annexed, Figure l is a top view of the machine in position to saw the trunk of a standing tree. section of the saw-carriage. Fig. 3 is a view of one of the standards and the box in which it is held and vertically adjusted. Fig. 4 is a view showing the treesaW-guide. Fig.5 is an end elevation, showing the machine employed to saw a log while in a horizontal position. Fig. Gis a view ofthe slotted standard.

The saw-carriage A is mounted on rollers b, which traverse a track composed of the two side rails, C, secured together by endpieces, C. This track-frame is supported on four standards, B-o-ne at each corner-and is provided at each of said corners with a box, cl, having a set-screw, d', by means of which each leg may be separately and independently adjusted in a vertical direction, thereby'enabling the track-frame to be set level regardless of the uneven nature of the ground, as indicated in Fig. 5. The sides o of the box, in which the rollers b have their bearing, project downward, and constitute a flange on each side, which sets astride of the track-rail. The slide on the sawcarriage, `in which the saw-head D reciprocates, consists ofthe upper and lower parallel bars, E, each of which is faced with a steel plate, e. '(See Fig. 2.)

At the front end. of the sawcarriage is a guide, f, through which the saw F passes. Another saw-guide, G, has two prongs and a head, and the prongs are driven into the tree. The saw then passesbetween the prongs, and

4 is thereby supported until it has made a cut and enters the tree. One of the beams, which forms a side of the saw-carriage, extends, as at A', at the rear end, and has at said extended end ahead, H, which carries a shaft, h, provided with two cranks, h and h2. Each crankarm is made of two pieces, one of ywhich is Fig. 2 is 'a crossanced on the saw-carriage.

sired point, thereby enabling the 'crank-arms to be adjusted longer or shorter. The cranks are so arranged that one man may handle both. A pitman-rod, I, connects the reciprocating saw-head D with the crank 7i', and thereby when the cranks are turned motion is given Athe saw F. A

Means to impart motion to the saw-carriage, so as to move it as fast as the saw makes a cut in the tree, and to give to the saw the desired pressure against the tree, consists of a cord,

lo, attachedto the side of the saw-carriage, and

extending toward the end of the track, where extends up to and overa pulley, m, on top of the standard B, and from thence hangs down,

preference a small bucket, to contain stones or similar material, is employed' as a weight. This weight, it will be seen, will constantly draw on the saw-carriage. s

It is important to so attach the cord to the saw-carriage that the point of attachnlent may be conveniently changed or adjusted, in order that the draft of thel cord may be evenly bal- If the cord be attached at a given xed point on the carriage, it may serve to draw it evenly (so that the flanges c at the rollers on each track will not bind thereon) while sawing a small tree, or while sawing the tree when the machine is close thereto; but when sawing alarge tree, or when sawing a tree while the machine is not in close posi-tion, the same given point for the attachment of the cord will not eect a balance or even draft on the saw-carriage. I

therefore provide a rod, N, whose ends arel .it passes through a pulley, Z, and from thence .and'has a suitable weight,\k, attached. By

made fast to the side beam of the saw-carriage.

This rod extends lengthwise of the said carriage. A hook-gripper, fn, is attached to the end of the rope, and hooks around the rod. This hook-gripper has suitable means, n', by which it may be tightened or set fast on the rod. By this arrangement of rod and hookgripper adapted to slide on the rod the point of attachment of thecord may be readily changed,- and it may be adjusted anywhere along'the length of the saw-carriage to suit the work for the time being.

As heretofore described, the machine is adapted particularly l'or sawing the trunks of standing trees, the snw moving or making a cut in a horizontal plaine.

In Fig. 5 ot' the drawings the machine is shown :trrnnged to suw timber while in u horizontul position, the sftw moving or making zi cut in :i vertical plane. One ofthe standards has :t vertical slot. p, through which a pivotpin. q. passes. This pin muy be adjusted up or down in the slot, and by menus ot' the nut q muy be set fast ut any elevation. A pendulum, R, is pivoted to the pin, und swin'gs in the guide formed by the two bars 1', which are separated to allow the pendulum to swing between them. A bruce, r', has one end bolted to the projecting ends ofthe bars, and the other end secured to the lower side of the track-rail, in which position it is out of the way of the ilnnge c of the-roller-box. This construction ull'ords stoy to the pznts und prevents the saw from tilting sidewise. A pitmnn, S, connects the lower or swinging end ofthe pendulum-and the crunk h2.

It should be here stated that when the machine is employed so that the saw will cut in :t vertical plune, the pitmnn I mustbe disconnected from the ernnk h', and the smv-curriage should be brought in position, close as possible to the slotted standard, und then secured to said position by means of pins u, passed through the truck rails Gland through the fiange c of the roller-box. The saw F is connected to a, link or arm, T, which is connected to the pendulum.

It will be seen that when turning the cranks, the pendulum will swing and impart motion to the saw, which at first will move through the two prongs of the guide G.

Having described my invention, I claim as new and desire to secure by Letters Patent ofthe United Statesl. In :L sturing-machine, the combination, with the saw-carriage, of :L rod, N, extending lengthwise of the carriage, and having its ends made fast thereto, a cord to which 2t weight is suspended, and a gripper. n, connecting one end ofthe cord and the said rod, the gripper being adapted to slide on the rod, asset forth.
